ATK Engines VCM5 87-95 Remanufactured Long Block 350 Crate Engine

ATK's VCM5 is a remanufactured 350 long block built for 87-95 applications, rated for use up to an 8,500 lb. GVW. The core goes through a full teardown, with the heads, block, crank, and cam all remachined and the wearing parts replaced, then every finished unit is individually tested rather than sample-checked. What the remanufacturing covers Each engine is pressure-tested, with the water jacket run at 30 lbs. of air pressure to rule out coolant leaks, then spun at 400 RPM with oil lines attached in a final check that reads compression on every cylinder, confirms oil pressure and flow, and lets the rear main seal be checked for leaks before it ships. This engine uses four-bolt main caps and a 1-piece rear seal, with the valve cover bolts running through the center of the cover rather than around the edge. What comes with it A new oil pump and the gaskets needed to finish the install travel with the long block. Oil pan and timing cover are installed. Confirm valve cover inclusion with us before ordering. Common questions Is this a new engine? No, it is remanufactured: disassembled, remachined, reassembled, and individually tested. Does it carry a warranty? ATK backs its remanufactured engines with a warranty. What's the GVW rating? ATK rates this build for vehicles up to 8,500 lbs. GVW, so confirm your truck or van falls within that rating before ordering. What tests does each unit pass? A water-jacket pressure test and a 400-RPM spin test that checks compression, oil pressure, and oil flow on every cylinder.
